What steps will reproduce the problem?
1. Install Chrome Version 31.0.1650.57 m
2. Go to https://code.google.com/p/shellinabox/
3. The basic interpreter demo shows a white screen.
This behaviour (blank schreen) is also observed on my own installations of
shellinabox.
What is the expected output? What do you see instead?
When doing the above in with FireFox 21.0, I see the basic interpreter, just
like a did with previous versions of Chrome.
What version of the product are you using? On what operating system?
Chrome Version 31.0.1650.57 m on Windows 7.
I run shellinabox-2.14 on my own server. Not sure about the version of the demo
on https://code.google.com/p/shellinabox/
Please provide any additional information below.

Same problem on OSX. Shell in a box doesn't work with v31 but works fine with
v30

Same problem, Firefox Portable ESR 24.1.1 shows the console.
Internet Explorer 64-bit 11.0.9600.16428 doesn't work either.
Running from my Raspberry PI, installed from Raspbian's repository.

The problem seems to be that the program is trying to determine a character
width by writing an nbsp into a hidden pre named 'cursor' and reading back the
clientWidth of the element. For whatever reason, the width comes back as zero.
That causes a divide by zero later on on the resize function, and eventually
crashes chrome. From the comments in the code, it looks like the clientWidth
can sometimes not be valid so the code tries to grab the width into a variable
at init time. In this version of chrome, the width isn't valid at init time
either, so a zero gets cached.
This is the first time I've ever looked at javascript, so I'm afraid I can't
say how to wait for the clientWidth of cursor to be valid, but I've worked up a
small patch that checks for the zero width and tries to deal with it. This is
probably not the right way to do it, but it gets the shellinabox code back up
and running for me.

Same problem here
ShellInABox version 2.10 (revision 239)
Google Chrome Version 31.0.1650.57
Not sure how to apply that diff file. If I look at it's contents it would
appear that the file is attempting to modify vt100.jspp from the following
location?
+++ /home/malakai/mud/shellinabox/shellinabox/shellinabox/vt100.jspp
however I can't find a vt100.jspp file on my box at all to run this patch
against.

Dear #5:
I have tested the patch and found it satisfactory ;)
Thanks!
Dear #6:
What I did (Ubuntu 12.04):
$ git clone https://code.google.com/p/shellinabox/
$ cd shellinabox
$ wget <url of the patch on a pastebin>
$ patch -p1 --dry-run < my.diff
< check that everything applied ok >
$ patch -p1 < my.diff
$ dpkg-buildpackage -b
$ sudo dpkg -i ../shellinabox-2.14-1
$ sudo service restart shellinabox
Obviously, YMMV depending on your distro and/or installed packages.

Thanks #8 that gave me enough info to apply the fix #6 posted
For any other linux nobs I would add the following
probably not necessary but;
$ sudo apt-get remove shellinabox
after applying patch be sure to check dependencies first. I was missing quite a
few
$ sudo dpkg-checkbuilddeps
so for the full script as follows;
$ sudo apt-get remove shellinabox
$ git clone https://code.google.com/p/shellinabox/
$ cd shellinabox
$ wget <url of the patch on a pastebin>
$ patch -p1 --dry-run < my.diff
< check that everything applied ok >
$ patch -p1 < my.diff
$ sudo dpkg-checkbuilddeps
# install any missing dep: sudo apt-get install [dep]
$ dpkg-buildpackage -b
$ sudo dpkg -i ../shellinabox_2.14-1[arch]
be sure to change /etc/defaults/shellinabox
SHELLINABOX_PORT=[port]
SHELLINABOX_ARGS="--no-beep -s /:SSH:[ip of host]"
$ sudo service restart shellinabox
and thanks again #6

Patch works for me too.
I also added the following to remove the invalid XHR setRequestHeader calls:

Im having this exact same problem but I dont understand how to apply the patch.
#8 and #9, where is the shellinabox directory Im supposed to start at?
I guess Ill just created a directory named shellinabox for now. But now when I
try doing "patch -p1 --dry-run < my.diff" I get this:
can't find file to patch at input line 3
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|--- shellinabox-2.14/shellinabox/vt100.jspp 2012-04-21 10:30:44.000000000
-0700
|+++ /home/malakai/mud/shellinabox/shellinabox/shellinabox/vt100.jspp
2013-11-23 20:43:24.531934272 -0800
--------------------------
It then asks me to choose a file to patch.. ok.. so I pick
shellinabox_2.14-1_amd64.deb which is in the same directory as everything else.
After this, it gives me the output:
patching file shellinabox_2.14-1_amd64.deb
Hunk #1 FAILED at 175.
Hunk #2 FAILED at 1157.
Hunk #3 FAILED at 1531.
3 out of 3 hunks FAILED -- saving rejects to file
shellinabox_2.14-1_amd64.deb.rej
And lastly, dpkg-checkbuilddeps isnt even a usable command... Im using debian
linux 7.2 64x.
Please help! These instructions make no sense :(

I applied the patch given by #5 without any modifications, on archlinux, and
it didn't fix the blank screen issue for me, in Chrome 32.0.1700 (windows 7,)
and with shellinabox 2.10 (revision 239.)
Does anyone have any advice here? Were the modifications given by other users
necessary? Wasn't sure how to make them so I just used the orignal .diff..

Correction, I'm using 2.14, but shellinaboxd --version outputs:
"ShellInABox version 2.10 (revision 239)"
For some reason.

I've a patched repo with the pre-built debian package binary for those
interested. It includes this my.diff.
